SPECIFICATION forming part of Letters Patent No. 735,617, dated August 4, 1903. Application filed June 2, 1902. Serial No. 109,893. (No model.)

To a/ZZ whom it may concern.'

Be it known that I, WILLIAM RUSSELL STRICKLER, a citizen of the United States, and a resident of Jewell, in the county of Jewell and State of Kansas, have invented a new and Improved Hoist, 'Raised Track, and Dumping Device, of which the following is a'full, clear, and exact description.

The invention relates to devices for loadinghay, grain, and other materials intobarns or other buildings and places; and its object is to provide a new and improved horse-power hoisting device which is simple and durable in construction, very effective and automatic in operation, and arranged to utilize the power applied to the fullest advantage, and to automatically trip olf a load and cause return of the load-carrier to the starting position. i

The invention consists .of novel Vfeatures and parts and combinations of the same,fas will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a. part of this specification, in which similar charactersof reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the improvement as applied for loading hay into a barn, the latter being shown in section. Fig. 2 is a front elevation of the same. Fig. 3 is an enlarged sectional side elevation of the carriage and the locking device for the same. Fig. 4c is an enlarged cross-section of part of the tripping device. Fig. 5 is a sectional side elevation of the same. Fig. 6 is a side elevation of a modied form of the hoisting-drum; and Fig. 7 is a side elevation of another modified form of the hoisting-drum combined with the tripping device, parts being shown in section. l

The vertically-disposed shaftA is journaled in a suitable step B and ina bearing carried by the overhead framework B2, projecting from the outside of the building B, into which the hay or other material is to be transferred or loaded.

On the lower end of the shaft A is arranged the usual sweeper A for attaching a horse or' team to turn the shaft A, and on the upper portion of the latter is mounted to rotate Vfresh load.

loosely the hoisting-drum C, on which winds and unwinds one end of the hoisting-rope D, supporting at its other end the load-carrier E in lrhe shape of a fork or like device for carrying the load. The drum C i`s caused to rotate with the shaft A when the rope D is to be wound up on the drum C for carrying the- -tripping device and fulcrumed on the overhead framework B2. When the load is discharging from the load-carrier E within -the building B, then the shifting-lever G is actuated, as hereinafter more fully described, to ,move the clutch member F'vout of mesh with the clutch member F t0 allow the drum C to rotate freely on the shaft A for the rope D to unwind, so that the load-carrier E returns to its starting position for receiving a The rope D passes from vthe drum C and lthrough a guide I toward the building and underfa pulley l', both'held on the overhead framework B2, the rope then extending upwardlyto pass over a pulley I2, held in the upper portion of the building B, and then the rope passes through the opening B in the building to the inside thereof and over a pulley 1S, held on the inner end of a guideway J, as plainly indicated in Fig. l. The rope then returns from the pulley I3 in anA outward direction and passes over a pulley I4, journaled in a carriage K, mounted to travel on the guideway J, above mentioned.. The rope extends from the pulley I4 downward to carry at its lower end the load-carrier E.

The carriage K is normally locked in an outermost position by a locking device consisting, essentially, of a pivoted hook L, (see Fig. 3,) engaging a Vfixed hook L', attached to the guideway J. The heel of the pivoted hook L is formed with a segmental gear-wheel L2 in mesh with a segmental gear-wheel L3, formed on the heel of a cam L4, mounted to turn in the carriage K and adapted to engage and clamp the rope D in the said carriage adjacent to the pulley I4, as will be readily understood by reference to Fig. 3. When the carriage K is in a locked position, as shown in said Fig. 3, then the cam L4 is out of engagement with the hoisting-rope D, so that the latter freely passes over the pulley I4; but when the drum C winds up the hoist-ingrope and the load is carried upward by the load-carrier E on the outside of the buildingr and the latter is within a short distance of the pulley I4, then a button Dl on the rope D movfs in contact with the pivoted hook L and swings the same upward out of engagement with the fixed hook L' to unlock the carriage. As soon as the carriage is released it begins to travel on the track, and as the weight of the load will cause the button D' ou rope D to move slightly away from the pivoted hook L the said hook will drop by gravity and in so doing turn the cam L4, so that the latter clam ps the rope D in position on the carriage K, with the load suspended immediately under the pulley I4 by the carrier E. A further winding up of the hoisting-rope D on the drum C now causes the carriage K to continue to travel with the load inward along the guideway J until the loadcarrier istripped and releases its load within the building B, so that the load falls to the desired place. At the time this takes place the shifting-lever G is actuated to move the clutch member F' out of engagement with the clutch member F for the drum C to rofate loosely on the shaft A to allow unwinding of the rope for the return movelnent of the parts.

The trippingdevice referred to is arranged as follows: One end of the tripping-ropeN is secured to the trip 1' of the load-carrier E, and the said rope extends over a pulley N', held on the outer end ofthe guideway J, and

the said rope extends through an eye N2 in a' weight N3 and is secured to an eye N4 at one end of a spring N5, secured to the building B. The end of the rope extending from the eye N4 is secured to the tripping-lever G', fulcrumed on the overhead framework B2 and pivotally connected with the shifting-lever G. The inner end of the tripping-lever G' carries a rope G2, extending downward to be within convenient reach of the operator for pulling the tripping-lever G' so as to impart a swinging motion to the shifting-lever G whenever it is desired to move the clutch member F' back into engagement with the clutch member F.

The extreme inner end ofthe tripping-lever G' extends into a guideway G3, (see Figs. 4 and 5,) attached to the building B, and the said innerend of the tripping-lever is adapted to engage a spring-catch G4 for holding the inner end of the lever in an uppermost position' when pulled into this position by the action of the rope N at the time the carriage K moves into an innermost posit-ion on the guideway J. It is understood that when the car- -riage K moves inward on the guideway J, as

above explained, the rope N is carried along by the trip of the load-carrier, and it finally draws up the weight N2 and stretches the spring N5, and when the carriage K reaches about an innermost position the rope N exerts a pull on the inner end of the trippinglever G' to canse the shifting-lever G to swing the member F' out ot' engagement with the member F, for the purpose previously described. By the swinging motion of the inner end of the tripping-lever G' the latter is locked in place by the spring-catch G4 and remains in this position until pulled downward by the operator pulling on the rope G2.

The spring-catch G4 is preferably provided with a rope G5, also under the control of the operator, to draw the spring-catch G4 out of the path of the tripping-lever G' previous to pulling the rope G2.

When the carriage K is moved back from its innermost position to an outermost position, then the rope N is drawn taut by the weight N3. In order to draw the carriage K back into an outermost position, I provide a counterbalancing device consisting, essentially, of a rope O, connected with the carriage K and extending through an eye O' on the outer end of the guideway J, the rope then extending around a pulley O2, secured to the outside of the building B, the rope nally winding on a drum P, journaled in suitable bearings on the outside of the building, as plainly indicated in Fig. 2.

The drum P is provided with a similar drum P', on which winds a rope P2, extending downward and carrying a weight P3. When the carriage K moves inward, the rope O causes rotation of the drums P and P', so that the rope P2 is wound up, and when the load is dropped off the load-carrier then the weight P3 and rope P2 cause a turning of the drums P' and P in an opposite direction to wind up the rope O, and thus draw the carriage K back into an outward position. When the carriage moves into an outermost position, the pivoted hook L can engage the fixed hook L', and in doing so imparts movement to the cam L4, so that the latter releases the hoisting-rope D, and the weight of the loadcarrier now causes the latter to move downward to the starting position, thus drawing the rope D tant.

The drum C may be made asillustrated in Fig. b' and formed of two sections C and C2 of dierent diameters for the hoisting-rope to first wind on the small section C2and then on the larger drum C', as will be readily understood by reference to said Fig. 6. By this arrangement the load is hauled up slowly from the ground to the carriage K, and then the latter is moved quickly inward over the guideway J, as the rope then winds up on the larger section C'.

In the modified form (shown in Fig. 7) the hoisting-drum C3 winds up the hoisting-rope D the same as above described in reference to Figs. 1 and 2; but inladdition this hoisting- ICO IIO

sis

drum is provided with a tripping device as follows: On the top of the drum C3 is arranged a drum C4, in which is secured a spring Q, connected by a small clamp or knot tothe tripping-rope Q', which extends through the spring Q and isconnected to the shifting-lever R, engaging the clutch member F2, mounted to slide on and to turn with the shaft A, the said clutch member being adapted to engage the clutch member F5, secured to the top of the drum C4. Now when the hoistingrope D Winds upon the drum O3 the rope Q unwinds from the drum C4, and when the carriage K nally reaches an innermost position on the guideway J then the rope Q is completely unwound from the drum C4 and now pulls on the spring Q4, so as to trip the fork first and Othen actuate the shifting-lever R to move the member F2 ont of mesh with the clutch member F3 to allow the drums C3 and C4 to rotate freely on the shaft A for the hoisting-rope D to unwind, for the purpose previously explained.
